An operational amplifier (often op amp or opamp) is a DC-coupled electronic voltage amplifier with a differential input, a (usually) single-ended output, [1] and an extremely high gain. Its name comes from its original use of performing mathematical operations in analog computers .
Schematic symbol for an OTA has inverting (V in-) and noninverting (V in+) inputs, power supply lines (V + and V −), two biasing inputs (I abc and I bias), and a single output current I out. The LM13700 is an integrated circuit (IC) containing two current -controlled operational transconductance amplifiers (OTA), each having differential ...

Schematic symbol for an OTA with differential input. Like the standard operational amplifier, it has both inverting (−) and noninverting (+) inputs; power supply lines (V+ and V−); and a single output. Unlike the traditional op-amp, it has two additional biasing inputs, I abc and I bias.
Operational amplifier symbol. The inverting and non-inverting inputs are distinguished by "−" and "+" placed in the amplifier triangle. V s+ and V s− are the power-supply voltages; they are often omitted from the diagram for simplicity but must be present in the actual circuit.

A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board.The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.
